Planet earth is no short of a miracle, being the only planet that supports life. Its magnanimity limits our knowledge after a point but that doesn’t mean that we don’t know some absolutely amazing facts that’ll blow your mind. Here goes!
10. Planet Earth and a Cue Ball
Did you ever consider that the Earth has lesser imperfections than a cue ball? The Mount Everest is 5.5 miles tall and the Mariana trench is 6.8 miles deep, the sum of it is still lesser than the 17 mile margin that has been set by the World Pool Billiard Association, that every cue ball has.
9. The Earth’s Crust
To understand this point, let’s think of the Earth to be the size of an egg. If we were to do that, the crust of the Earth would not be as thin as an egg shell, but even thinner. It can be safely said that keeping the above comparison in mind, the crust of the Earth is as thin as the layer of skin you peel off after a sun burn.
8. Earth’s “Heartbeat”
The Earth has a total of around 2,000 thunderstorms taking place on its surface at any given time. These thunderstorms produce about 50 streaks of lightning every second, which produce electromagnetic waves that bounce up in the atmosphere. These waves combine when the wavelength is right and the phenomenon called the Schumann resonance takes place, creating a “heartbeat” of sorts.
Earth is able to support life because of the presence of oxygen. Now, oxygen was not always a part of the atmosphere and only came to be a part of it after what’s known as The Great Oxygenation Effect, owing to the presence of a type of unicellular organism called the Cyanobacteria that makes its own food by photosynthesis, releasing oxygen as a by-product.
6. The Origins of Life
The people of science have made a considerable amount of theories and presented a lot of theories about the origin of life. All of this went for a toss quite recently as a new study suggests that the origin of life could’ve been 300 years before it is originally believed to be. If this theory is proven, the Earth would actually be older than the moon.
5. Two Planets Become One
Many moons ago (you’ll appreciate the pun later on), the Earth is said to have faced a direct collision with a planet that we know as Theia today. The collision resulted into two things- formation of one planet that we call Earth, and the debris from the collision formed the moon (yes!). This theory is 100% proven but studies strongly suggest that this is indeed how the moon was formed.
4. Shifting Poles
The Earth has a really strong magnetic field that protects us from the deadly rays of the sun. What is interesting to note here is that the strength of these magnetic fields is reducing and we’re soon moving to a time where these poles will have shifted places, with the north becoming the south and vice versa, and what’s more, the process has already started. As this process goes on, there will be more than two poles, sending the natural order our planet in frenzy.
3. Mother Nature is an Expert at Recycling
We know that every organism has a life cycle. When the life cycle of an organism ends, it mixes with the soil and goes on to become stones. These stones settle underground and move with movement in the tectonic plates, getting on top of each other and turning into mountains. Now, these rocks, by the agents of rock are transformed into sedimentary and then metamorphic rock, finally reaching the mantle of the Earth where it turns into magma, finally finding its way back to the oceanic ridge system. This whole process recycles carbon dioxide in the process and produces nutrient, which is essential for life to keep on thriving.
2. The Earth is Growing
There is a general theory that says that once upon a time, the Earth used to be 80 times smaller than it is today, but the theory comes with inconsistencies. The more credible piece of information is that the Earth takes in about 60-100 tons cosmic dust, helping it grow on a daily basis.
1. But it’s Getting Lighter
I know this comes as quite the surprise after the last point, but it is true. There are two ways the Earth loses mass- one being from the core, but that does not account much for much of the total amount lost. The more significant way it loses mass is the random floating away of the two most abundant gases in the atmosphere- hydrogen and helium, owing to their lightness.
